    Significance and Use

    The results of this test indicate whether or not a sheet steel will cause reboiling under one given set of enameling conditions and enable the enamel processor to establish a possible source of imperfections in the finished coating.

    This test method is normally used to test samples from lots, coils, or lifts of sheet steel which for some reason, production problems, defects evident on enameled parts, or production experience are suspected of causing defects in enameled ware which have the appearance of reboiling. It is often used to establish whether a problem exists with the bare steel or other factors such as the porcelain enamel, processing contamination, and so forth.

    1. Scope
